- Sample taken at OC
- The oil used was the old formulation of Pennzoil Ultra which was discontinued over a year ago. Not sure exactly when. I have about 2 more OC's worth of it.
- Filter used was PureOne PL14610 replaced with a Fram ToughGuard. (Do we still argue over that here?)
- Yes, OCI was over a year. Wife uses the car and makes short trips (under 10 mi) just about every day. Took a long time to get up to 9k.
- TBN and viscosity appeared to have benefited from 1 qt of makeup oil about 9 months into the OCI.
- Yeah, Al is still a little high. Maybe b/c of the short trips?
- Not planning to extend the OCI much further than this if at all. Maybe 10k as a nice round number.
As always, any thoughts, comments, questions, etc are welcomed.
